We look at the division of 212317 by 53 
We're looking to find how many times 53 goes into 212317.

On to step 1:
53 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 53

On to step 2:
21 divided by 53 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 53

Let's proceed to step 3:
The number 53 fits into 212 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 212 from 212 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 53

Moving on to step 4:
If we divide 3 by 53, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 53

Let's proceed to step 5:
If we divide 31 by 53, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 400.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 53

Advancing to step 6:
The number 53 fits into 317 5 times, leaving a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 4005.0
If we take 265 away from 317, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
When dividing 520 by 53, we get 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 4005.9
The remainder is 43 after subtracting 477 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 8:
53 goes into 430 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 4005.98
The remainder is 6 after subtracting 424 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
If we divide 60 by 53, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 4005.981
Subtract 53 from 60 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
If we divide 70 by 53, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 4005.9811
If we take 53 away from 70, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 4005.9811 with a remaining 0.00017.
